Nhileit CIIthe Wide ball portion of the sole, it remains in that position, and whenthe roll then passes to the narrower part of the sole near the. toe, itdoes not apply the pressure that it would if the toe were central.Similarly, when the roll tips to the other side or" the sole, it beginsto act on that side with the toe in an abnormal position, until itsuddenly effects a displacement of the shoe in the opposite direction tothe limit permitted by the toe rest. It will thus be seenv thatprovision merely for lateral di placement of the shoe in response topressure, as by slipping of the toe on a toe test, does not afford anymaterial improve ment in the conditions under consideration since thereis nothing which acts to return the shoe or to centralize it. Lateralmovement of the shoe in one direction can compensate only for verticalmovement of the inclined roll in one direction, for example when theroll moves upward, and in order properly to counteract the tendency forthe roll'to rub on the sole when it moves down ward, a lateral movementof the shoe in the opposite direction is required. Even, therefore, iftoe rests as heretofore constructed afforded provision for substantiallateral movement .of the shoe, conditions affecting the action of theroll on the edge of the sole would not be materially improved, and insome respects would be still more detrimental to good work.

The present invention accomplishes a very important improvement inleveling machines by provision for substantial relative movement of theleveling tool and the shoe laterally of the shoe under conditions thatinsure the proper action of the tool on the different portions of theshoe. In one important aspect, the invention provides for relativemovement of the tool and the shoe laterally of the shoe in differentdirections at different times in the progressive action of the toolalong the side of the shoe, thus avoiding objectionable rubbing of themargin of the sole where pronounced variations in the contour of thesole are encountered by the tool, and at the same time maintaining sucha relation between the tool and the shoe as to insure proper levelingpressures on the different portions of the margin of the sole. In theconstruction herein shown as an illustrative em; bodiment of theinvention'provision is made for relative yield of the shoe and the toollaterally of the shoe, in response to such increase of pressure asresults, for example, when the tool encounters the wider and higherportions of the sole, under control of resilient means which acts, aspermitted, to effect relative return movement of the shoe and the tool.For the purposes in view the machine herein shown comprises of the shoeon the toe rest.

in its organization a leveling roll which is yield-able heightwise ofthe shoe, and a shoe. support having shoe positioning and controllingmeans which is resiliently yieldable laterally of the shoe. Moreparticularly, in the illustrative machine provision for such lateralyield of the shoe is afforded by the use of a toe supporting cushion orrest of soft rubber of such thickness as to be deformed or distorted toa substantial extent in response to the pressure of the leveling toollaterally of the shoe. While permitting sufficient displacement of theshoe to avoid objectionable consequences such as heretofore encountereddue to the slipping of the roll on portions of the margin of the sole,for example in passing fromthe shank to the ball of the shoe, this toerest also tends constantly to return the toe to a central position. Thisnot only insures that the shoe will be properly cen tralized as the rolltips from one side of the sole to the other, but also serves to preventthe roll from rubbing on the sole as narrower portions of the sole arepresented to it, while at the same time insuring a proper degree ofpressure on the narrower parts of the sole as well as on the widerparts. A still further advantage in'the use of this toe rest is thatwhen the roll is horizontal it permits the shoe to be depressed somewhatas the roll acts on the high portions of the sole, and presses the shoeup toward the roll as the latter passes to the lower portions, thuscontributing to an even rolling action.

A further very important object a'ccomplished by the present inventionis the elimination of objectionable results heretofore encountered dueto the rubbing of the too The soft rubber toe rest clings to the'surfaceof the upper, even when the shoe is displaced laterally to a veryconsiderable extent. In other words that portion of the rubber which isin contact with the shoe moves with the shoe, and there is thus nodanger of damaging the surface of the upper.

These and other features of the invention comprising certaincombinations and arrangements of partswill be understood from thefollowing description of a pre ferred embodiment thereof selected forpurposes of illustration and shown in the accompanying drawings, inwhich,

These shafts are ree able bymechanism not necessary to be described here as it is not a part of thepresent invention. Reference may be made to the application abovementioned fora of it, or to the patent No; 889,- l I une 2, 1908, on theapplication of E. E. inliley, which shows a similar meihauism. Itsoperation may, be briefly described by saying that a main cam pro ducesa standard tipping cycle, and other adjustable cams modify'this "tippingcycle accord ng to their settings by the operator.

'lhe'shoe is held' on together at 60 to permit adjustment toaccommodate, different lengths of shoes and 'mouuted on a. shaft 62which is rocked by link and lever mechanism operated by 1,011,301 issuedDec. 12,1911 on the appli- 1,239,664, on the application of cation of E.Winkley, andissued. Sept. 11, 1917 VJ. C. Easter, and need not scribedhere.

The leveling rolls are resiliently forced down upon the shoe bythepressure of springs 68 mounted in vertical channels in the mainframe. These springs press at their bottom ends uponvlevers their rearends on the main frame at 72 and at their front ends to verticallyextending links 74 which are pivoted to the leveling arms 12. The upperends of the springs are engaged by plungers 76 provi ded with lugs 82with which the. arms be further de- St on the rock-shaft 86,-which is,mounted or. the frame; are in engagement.

The rock-shaft 86 is operated'by a link 90 pivoted to an arm 91 on theshaftand to the end of a ing a roll 96 contacting witha cam- 98 mountedon the mainshaft25. The lower arm of the link 94: has a slottedbearingon the main shaft to hold it in position. The

In the joint application above referred to,-thi's structureis very'fully described and: claimed.

The leveling roll 20 itself" is mounted: in a cariage having are orsegment-shaped lateral extremities at112uhereby it may be rotated abouta vertical axis in thehead and held in adjustable position by a screwand slot arrangement at ll lf This enables the roll to be adgusted tosurtcertain kinds and conditions of work.

This rubber in the form shown in Fig. 2, is substantially flat ontop,not beinghoh lowed out in any effort tofit shoe. The ordinaryjacking pressure exerted through the mechanism at 12% which is 'wellknown and need not be further describedhere, will cause: the toe to sinkappreciably into the rubber before the leveling operation begins, asshown'at 126. a

Figs. 3 and i show two modified forms of rubber block which have certainadvantages. The block shown in Fig. 3 has a slight depression 128 toserve as a gage for the longitudinal positioning of the shoe. in thejacking operation. It is not contemslate at that this depression I shallnecessarily it the toe; it simply serves as a mark that load, but notsul'istantially more. As soon as the strong springs 68 come intoac-'tion, the, effect of the plungers is masked deformed by amounts the toeof-the the operator can see. Fig. 4 shows a rubber block with a raisedrib 130 for the same purpose.

In order to understand the advantages of this invention it is necessaryto consider the nature of the pressures and reactions in the levelingmachine. The trunnions at 1% are horizontal, so that the levelingarms 12can move only in a vertical plane. The axis at 62, on which the jacksrock. is parallel to the axis at 1%, so that the relative movement ofthe shoe and leveling roll in a direction lengthwise of the shoe is alsoin the same vertical plane. \Vith the parts in this relation and withthe leveling roll inclined to the horizontal as it frequently is inoperating along the margin of the sole at the side of a shoe, thepressure of the roll tends to swing the shoe laterally about the heelpin, and this tendency is considerably increased as the roll encountersthe wider and higher portions of the sole, as in passing from the shankto the ball of the shoe, and is thus forcedto swing upwardly. If it werenot for provision for substantial relative movement of the roll and theshoe laterally of the shoe at such times, the roll by its upwardmovement in a direction in clined to its axis would rub on the margin ofthe sole with danger of objectionable re sults such as hereinbefore setforth. The soft rubber cushion or toe rest 122, however, yields with theshoe. In response to the pressure of the roll, to such an extent as tocounteract the tendency of the inclined roll to rub on the sole. Inother words, the result of the lateral yield of the shoe and thevertical yield of the roll is, in effect, a relative yield substantiallyperpendicular to the surface on which the inclined roll is operating, sothat the roll has simply a rolling action without substantial rubbingaction. Moreover, where the contour of the shoe results in a downward'movement of the roll, the resilient toe rest acts to effect a returnmovement of the shoe laterally as permitted by the lessened resistanceof the roll. and thereby counteracts the tendency of the roll to rub onthe sole at that time also, while assisting in maintaining properleveling pressure on the margin of the sole. Similarly, when the rolltips from one side of the shoe to 'the other, the shoe isai'itomatically centralized, so that it is presented in proper relationI for the roll to begin its operation on the opposite side of the sole.An important factor in these desirable results is the fact that the softrubber toe rest clings to the surface of the upper so that the shoe asit yields carries the top of the resilient toe rest with it, and afurther very important advantage in thisis that no rubbing takes placebetween. the and the. toe rest, so

that dangerof damage to the surface of the upper is avoided.

There is still another important advantage in the use of a toesupporting cushion or rest such as herein described.

According to the former practice, as hereinbefore explained, it has beenthe custom to provide toe rests which were shaped, as well as might be,to the shape of the toe of the shoe, for of supporting the shoe againstthe lateral pressure, and avoiding the scratching and rubbing consequenton any yielding to such pressure. It being practically impossible toprovide and use a toe rest exactly fitted to each shoe, this onlypartially met the rub bing difficulty, and moreover, when small toeswere put into rests too large for them, the shoe had a tendency tosettle down and bacl: into the rest so far that the rest instead of theshoe tool; the pressure of the roll as it tipped around the toe.Inasmuch as a tipping of the roll around on the toe end of the soleisnecessary in order to shape the shoe properly at this point, the machinefailed to do good work in this regard under the described circumstances.Vi ith the machine of the present invention all shoes are aclred to thesame height on the soft rubber toe rest and proper and uniform treatmentof all shoes results.
